[JAVA3D] View and Scene synchronization bug still in Beta2

2000-03-31 Thread Shawn Kendall
In Java3Dbeta1, I found a synchronization problem between updating a transform on some geometry and updating a transform above the View. The update was performed in a behavior that used WakeupOnElapsedFrames(0). >From other posts later, I assumed the synch-ing problem was due to the bug announced

Hi Shawn, The synchronization bug 4313347 is fixed in FCS release. However it is too late for us to make it into the upcoming v1.2beta2. In FCS release, you will see that the view is much less jitter than before. But there is still a little bit jitter sometime, since Java 3D spec. don't gu

[JAVA3D] View point

2000-03-30 Thread Nicolas Trichaud
Hello, I'm working on a 3D visualization of dynamics data and I'm fighting against a viewing problem: To each visual component corresponds a view point (which moves with it)... and I'm not able to catch the structure of the view part of J3D! Does anybody have some tip?

Ok, my solution is to catch only Entry/Exit events (with USE_BOUNDS, not USE_GEOMETRY, because the former is much more precise). Set bounds to the size bigger a little bit that your model. Use the model as an arm object. The objects in the scene - as triggers. Surround both the arm object and the
